Dimethyl ether (DME) is a compound first introduced by Shell as chemical solvent for enhanced oil recovery (EOR). This study aims to investigate the efficiency of EOR using minimum miscible pressure (MMP) and viscous gravity number when mixed CO2 DME injected. Adding water-alternating-gas process reduces MMP number. Reduction in results conditions at lower pressures, which has favorable effect ...

Gas injection into carbonate formations is one of the most important activities to protect oil reserves that can guarantee a steady production. On-time injection of enough gas can result in the recovery of billions barrels of oil. In addition, it can preserve a huge amount of gas for the next generations. If the reservoir depth is shallow, or the reservoir fluid has a little amount of intermedi...

CO2-foam injection is a promising technology for reducing gas mobility and increasing trapping within the swept region in deep brine aquifers. In this work, consistent thermodynamic model based on combination of Peng-Robinson equation state (PR EOS) components with an activity aqueous phase implemented to accurately describe complex phase-behavior CO2-brine system. The module combined represent...

Abstract Enhancing oil recovery in reservoirs with light and high gas content relies on optimizing the miscible water alternating (WAG) injection profile. However, this can be costly time-consuming due to computationally demanding compositional simulation models numerous other well control variables. This study introduces WAG eq , a novel approach that expedites convergence of optimization algo...

Miscible viscous fingering occurs when a less fluid displaces more one in porous media or Hele–Shaw cell. Such flow instabilities are of particular interest variety applications flows and displacements subsurface energy environment systems. In this study, we investigate the miscible dynamics experimentally using water to displace glycerol sealed cell with two wells located it instead at boundar...

Carbon dioxide (CO2) flooding is one of the most important and used enhanced oil recovery (EOR) method because it does not only increase efficiency but also as an underground CO2 storage. It considered a very complex involves knowing fluid phase behavior with different concentrations. should be noted that swelling (volume increase) dissolution carbon has significant effect on recovery. When thi...

Chemical reactions can impact mixing in partially miscible stratifications by affecting buoyancy-driven convection developing when one phase dissolves into the other one in the gravity field. By means of combined nonlinear simulations and experiments, we explore the power of an A + B → C type of reaction to either enhance or refrain convective dissolution with respect to the nonreactive system ...

Carbon dioxide flooding is a strategic replacement technology for greatly enhancing oil recovery in low-permeability oilfields, which includes social benefits resulting from carbon emission reduction and economic owing to the improvement of recovery. Therefore, it great significance develop apply CO2 storage petroleum industry. In reservoir conditions, usually under supercritical state, present...

Geological sequestration of CO2 through Enhanced Oil Recovery (EOR) presents an opportunity to achieve significant emissions reductions. However, there is considerable uncertainty over the amount of CO2 that can be stored over the economic life of an EOR project. This paper presents the development of a model that provides first-order cost estimates, sensitive to key site-specific or project-sp...
